Add support to local comflowyspace GUI connect to remote server comfyUI

I would be wonderful if I can use comflowyspace on my macbook air but connect to Tesla 100 GPU on my company's server or 4090Ti desktop in my office.

Look for network configuration and client-server communication code in the codebase, likely in src/ or a services/ directory. Understand how the local GUI currently connects to ComfyUI and what APIs are exposed. The goal is to modify the connection logic to allow specifying a remote server address, handling authentication, and managing data transfer between the local frontend and remote GPU backend.
